Abstract: ABSTRACT OF THE DISCLOSURE         The disclosure sets forth a process for isolating a specific nucleotide sequence containing genetic information, synthesis of DNA having the specific nucleotide sequence and transfer of the DNA to a host microorganism   The process involves isolation of a selected cell population, extraction of intact mRNA from the cells, purification of intact messenger RNA from the extract and subjection of the purified extract to the action of reverse transcriptase in the presence of the four deoxynucleoside triphosphates needed to synthesize a complementary (cDNA) strand.  The ribonucleotide sequence is selectively removed and the remaining deoxynucleotide sequence is incubated with reverse transcriptase or DNA polymerase in the presence of the four deoxynucleoside triphosphates to form a duplex cDNA structure having its comple menary strands joined together at one end by a single stranded loop.  This product then is treated with single strand specific nuclease to cleave the single stranded loop, the resulting double stranded cDNA is extended in length by the addition at both ends of a specific DNA containing a restriction enzyme recognition site sequence, and the extended cDNA is treated with a restriction endonuclease to produce self-complementary single stranded ends at the five-prime termini of each strand in the duplex.          A plasmid DNA having a recognition site for the same endonuclease is treated with the enzyme to cleave the poly-nucleotide strand, the 5' terminal phosphate groups from the resulting self-complementary single strand nucleotide sequences at the five-prime termini are removed and the prepared cDNA   and plasmid DNA are incubated in the presence of DNA ligase, so that a viable closed ring of plasmid DNA can only occur if a segment of cDNA is included the cDNA-containing plasmid then being introduced to an appropriate host cell.  Pure bacterial strains containing the recombinant plasmid are grown up and isolated.  By this procedure, large amounts of recombi-nant plasmid DNA may be prepared and the specific cDNA sequence reisolated therefrom by endonucleolytic cleavage.

Abstract: ABSTRACT METHOD AND APPARATUS FOR HEAT TREATING This invention relates to a method and apparatus for surface hardening metals by means of a concentrated beam of electrons. The electron beam is directed and focused to a desired spot on the surface of the said workpiece and is caused to move incrementally from one to the next of a predetermined pattern of points on the work surface. The beam is directed to each point in turn for a predetermined length of time and moved from point to point at a relatively rapid rate. The pattern is projected over the desired surface of the work a predetermined number of times so that the material to be heat treated is brought above the transformation temperature and maintained below the melting temperature by close control of the electron beam parameters. A programmable computer retains in its memory a number of predetermined displacement patterns for the electron beam and controls all the electron beam gun parameters and all machine functions.

The improvements comprise a presettable memory device for storing control signals associated with the respective pre-determined channels, these control signals being used to control at least one operating condition of the signal receiving apparatus. A selectively operable preset circuit generates at least one control signal for storage in the memory device when the tuning stage is tuned to an associated channel during a preset operation.  A par-ticular stored channel identity signal is read out from the storage device and, concurrently therewith, at least one control signal associated with the channel represented by the read out channel identity signal is read out of the memory device.  The read out channel identity signal determines the channel to which the tuning stage is tuned, and the read out control signal, or signals, deter-mines the operating condition of the signal receiving apparatus for that channel.     -i-

Abstract: Abstract of the Disclosure An article of manufacture for use as as an implant in the animal ear to correct a faulty carriage of the ear occasioned by the presence of a skin-enclosed cartilage fault comprises a spring constructed of non-porous biologically inert material, the spring having outwardly divergent arms terminating in outer free ends and adapted to be forced together to present a narrow elongated spring outline for implantation  of the spring in the ear by insertion through a small incision in the skin of the ear with the free ends foremost and into a pocket previously formed bewteen the skin and carilage over a cartilage fault, so that the spring bridges the fault, the spring arms when free of applied force tending to return to their original divergent dispositions owing to the resiliency of the spring whereby when the spring is implanted in the ear, the spring arms resist displacement of the spring towards the incision.  The article is especially adapted for use as the implant in the implantation method in which a cannula-like sheath is inserted through the incision and into the pocket, so that the sheath bridges the fault, an elongated ear implant is inserted endwise in the sheath 9 and the. sheath is removed from the pocket and from around the implant to deposit the implant in the ear in bridging relationship to the fault.
